PISTON KIT 97-01 CR250 67.50, NAMURA NX-10025-4 HUSQVARNA

Namura Piston Kit - 67.50mm Bore - 1.00mm Oversize

This high-performance Namura piston assembly is engineered for superior engine performance and longevity. Manufactured with a high-silicon content hypereutectic cast aluminum material, it offers reduced heat expansion, tighter clearances, increased hardness, and a longer lifespan with reduced scuffing.

The piston features a machined, smooth piston crown designed to minimize carbon buildup, thereby increasing horsepower and improving fuel economy. For enhanced durability and minimal expansion, the crowns are hard anodized, making them 75% stronger than non-anodized versions and reducing the risk of cold seizures. This is further complemented by Teflon/Molybdenum coated skirts (MOS2) which significantly reduce friction and heat for added power and extended engine life.

Namura piston rings are designed to match OEM specifications, with available fractional oversize pistons to extend the life of your cylinder by renewing original clearances if slightly worn, avoiding costly sleeving.
